if/else jQuery with JSON

My JSON includes some pictures. I have gotten the pictures to work when they should and when they shouldnt. With the help of a if/else in jQuery. Now what I want to do is that if a image is displayed, so will some text. I want the "foto" the be dispalyed only if a image is displayed. The code below does not work. :/

---

var foto = post.foto var image = post.image;

// if a image is going to be displayed
if (post.image.length >= 1){
    img = '<img src="/images/' + image+'" alt="image">';
    if (post.foto.length >= 1){
        foto = "";
    } else{
        foto = "";
    }
// else if a image should not be displayed
}else{
    img = "";
}
